TEMPERATURE DEPENDENCE OF OPTICAL TRANSMISSION OF GERMANIUM SINGLE CRYSTALS
In this work, we investigated optical transmission in the wavelength range of 2-14 µm of low-resistance germanium crystals (1-3 Ω·cm) doped with donor and acceptor impurities in the temperature range from 86K to 523K. The values of the attenuation coefficients for investigated crystals are obtained....

| description | In this work, we investigated optical transmission in the wavelength range of 2-14 µm of low-resistance germanium crystals (1-3 Ω·cm) doped with donor and acceptor impurities in the temperature range from 86K to 523K. The values of the attenuation coefficients for investigated crystals are obtained. Minimum attenuation coefficients α of 0,0015-0,0231 cm^(-1) in the temperature range from 86K to 323K are characteristic for germanium single crystals doped with antimony in the range 2,1-11 μm. Studies have shown that the low values of α and the transmittance τ at a wavelength of 3,39 μm for Ge:Bi and Ge:Sb crystals make it possible to use these low-resistance germanium crystals for gas helium-neon lasers at temperatures from 86K to 323K. The temperature changes in the geometry of the crystal surface are investigated at the nanoscale level. It is shown that heating crystalline germanium leads to an increase in the diffuse reflection of radiation from the surface. The possibility of using the low-resistance germanium crystals doped with antimony as elements of infrared optics in the temperature range 86-373K has been demonstrated. |
